Embodiment Construction

[0040] The system for processing uplink control channel information in the present invention includes a scheduling request detection module, a discontinuous transmission detection module, and a reporting module connected in sequence; and an uplink control channel information acquisition module connected with the reporting module.

[0041] The uplink control channel information acquisition module is used to acquire uplink control channel information from uplink signals.

[0042] The scheduling request detection module is used to perform scheduling request detection when the scheduling request cycle indication result issued by the upper layer is valid, and notify the discontinuous transmission detection module after determining that the user equipment has not issued a scheduling request.

[0043] The discontinuous transmission detection module is used to detect the discontinuous transmission of the uplink signal; it is also used to perform discontinuous transmission detection whe...

Abstract

The invention discloses a method and system for processing uplink control channel information. The method comprises the following steps of: judging an uplink control channel mode adopted by UE (User Equipment) according to a discontinuous emission detection result at a base station side and the uplink control channel information reported by the UE and confirming the uplink control channel mode information reported by the base station side. The invention proposes a method and device for the discontinuous emission detection and the mode judgment of the uplink control channel mainly aiming at the uplink control channel processing of LTE (Long Term Evolution). Based on the discontinuous emission detection, different modes of a PUCCH (Physical Uplink Control Channel) are effectively separated, the hardware implementation complexity is lowered, hardware implementation resources are saved, the efficiency for decomposing the PUCCH information at the base station side is improved, the uplink control channel is rapidly received and processed and insurance is provided for the uplink and the downlink flows of the LTE.

Description

technical field [0001] The present invention mainly relates to the field of digital wireless communication, in particular to a method and system for processing uplink control channel information. Background technique [0002] The Physical Uplink Control Channel (PUCCH for short) is a very important uplink physical channel in the Long Term Evolution (LTE for short) system, and the PUCCH channel is responsible for carrying the period of the Uplink Control Information (UCI for short). Reporting, uplink control information includes: [0003] The HARQ-ACK is an indication signal of a Hybrid Automatic Repeat reQuest (HARQ for short). When the transport block (TB) sent by the base station to the user equipment (User Equipment, referred to as UE) cannot be normally demodulated and decoded by the UE, the UE will feed back a negative acknowledgment (Negative Acknowledge, referred to as NAK) signal to instruct the base station to retransmit the TB block; If the UE can demodulate and ...
